摘　　要：目标与背景红外辐射的差异是红外探测系统探测目标的基础。因此,研究目标与背景红外辐射的差异对红外伪装有着重要的意义。介绍了热红外伪装的原理。从目标与背景的辐射对比度出发,分析了辐射对比度与目标表面发射率以及目标与背景温差的关系,发现对于一定温差的目标与背景,伪装材料的发射率在一定范围内,都可以达到很好的伪装效果,温差越大,这个范围就越小。The difference of the infrared radiation between the target and background is the elements of IR detection system detect target.Therefore,the study on the difference of the IR radiation between the target and background becomes more and more important for IR camouflage.The principle of thermal infrared camouflage is introduced.Based on the radiant contrast ratio between the target and background,the relationship between the radiant contrast ratio and the emissivity of target and that between the contrast ratio and temperature difference are analyzed,and it is found that for determinate temperature difference between the target and background,using the camouflage material which the emissivity in some range will attain good camouflage effect.The bigger the temperature difference,the smaller the range.
